Woow! Amazing!!!Although these textures are not properly tiled, and in order to put this in the game with real time bumps, youll need to save the bump layer in a separate file and put it together with the other texture in someting like 3ds max. Other than that this is suberb!(really reminds me of quake 4, how you have done the beveling :)

That 3d stuff (on the sides, the "protruding" bevels) could either be really good for a game or really bad. It would look kinda weird on a flat surface without any real geometry to back it up. I love the subtle bump effect and the grid in the floor! Superb!
